Most of the building construction worldwide use bricks as building material for masonry construction. Use of geopolymer bricks using industrial waste is a sustainable alternative to conventional bricks. The present study assesses the feasibility of using red mud based geopolymer bricks in masonry for structural applications. Granulated blast furnace slag (GBFS) was used as a partial replacement of sand in casting bricks. Mechanical property of bricks was evaluated and the results analysed. The optimum percentage of red mud was found to be 30% but the bricks cast with 50% red mud too, exhibited good dry compressive strength of 8.7 MPa with 1:1 binder: aggregate ratio. In general, strength and stiffness of bricks increased when sand was partially replaced with GBFS. Ultimate strength and masonry efficiency of prisms cast with geopolymer brick and cement mortar proved to be better than those cast with geopolymer mortar.

全球范围内的大多数建筑都使用砖作为砌筑的建筑材料。使用工业废料使用地聚合物砖是传统砖的可持续替代品。本研究评估了将红泥基地质聚合物砖用于砖石结构应用的可行性。粒状高炉矿渣（GBFS）用作铸砖中沙子的部分替代品。对砖的力学性能进行了评估，并对结果进行了分析。发现赤泥的最佳百分比为30％，但也用50％赤泥浇铸的砖块在1：1的粘合剂：骨料比率的情况下表现出8.7 MPa的良好干抗压强度。通常，当用GBFS代替沙子时，砖的强度和刚度会增加。
